Australian citrus supply has fallen off this season. Bad-weather led to a poor harvest, forcing suppliers to import from overseas and increase their prices. In some cases, lemons have increased over 300%, making lemons quite the commodity.
Lemons are being imported from the US, meaning prices per kilogram have increased from around $4 to $13. Although many farmers have systems in place to accommodate for severe weather, sometimes these things just can’t be avoided. Stockpiled produce and hydroponic growing operations have not proven sufficient to keep the cold at bay.
Isolated, island nations are prone to price spikes—just last year the price of a single avocado reached $9.
